The exact procedure is the following
Details
On 8Gb Brocade switches, if the Boot PROM password is not set(or it is set and known) and need to recover root password (in case it was set previously and forgotten), then follow the below procedure to set all the passwords to factory default (Factory defined user IDs: root, factory, admin and user, Default password: password):
1. Connect the serial console to the SAN switch (or director). (Default serial console settings: Baud rate ├в 9600, Data bits ├в 8, Parity ├в none, Stop bits -1, Flow control ├в none).
2. Reboot the switch
3. Press ESC at the message ├в Hit ESC to stop autoboot: ├в , the Boot PROM menu displays with the following options:
1) Start system.
2) Recover password.
3) Enter command shell.
Option?
4. Type ├в 3├в to Enter Command shell.
1) Start system.
2) Recover password.
3) Enter command shell.
Option? 3
Boot PROM password has not been set.

5. Run the ├в printenv├в command to check the environment variables (This step is optional).
Sample output of ├в printenv├в from a Brocade 8Gb switch:
=> printenv
AutoLoad=yes
BootromVerbose=no
InitTest=MEM()

Sample output of ├в printenv├в from a Brocade 4Gb switch:
> printenv
AutoLoad=yes
ENET_MAC=00051E0343E3
InitTest=MEM()
LoadIdentifiers=Fabric Operating System;Fabric Operating System
OSLoadOptions=quiet;quiet
OSLoader=ATA()0x3c020;ATA()0x6b348
OSRootPartition=hda1;hda2
SkipWatchdog=yes
6. Set the environment variable ├в OSLoadOptions├в to single (or ├в s)
=> setenv OSLoadOptions single
(Note: On 4Gb switches, the setenv requires ├в =├в as well:
setenv OSLoadOptions=single )
7. Run ├в printenv├в command to verifyt the new value of ├в OSLoadOptions├в :
=> printenv
AutoLoad=yes
BootromVerbose=no
InitTest=MEM()
LoadIdentifiers=Fabric Operating System;Fabric Operating System
OSLoadOptions=single
OSLoader=ATA()0x8c047;ATA()0x14e978
OSRootPartition=hda1;hda2
SkipWatchdog=yes
baudrate=9600
bootcmd=setenv bootargs mem=${mem} ${OSLoadOptions};ataboot;bootm 0x400000

stdout=serial

Environment size: 652/4080 bytes
8. Run the command ├в boot├в ( on 4 Gb switches, run the command ├в auto├в )
=> boot
Note: The rest of the steps are same for all switches with Linux based FOS (ver 4.1 and above).
9. After the switch boot in single user mode, remount the / partition as read/write:
sh-2.04# mount -o remount,rw,noatime /
10. Mount the second partition to /mnt (this will get from the value of ├в OSRootPartition├в variable in ├в printenv├в output ├в usually it will be ├в hda2├в , that is, /dev/hda2)
sh-2.04# mount /dev/hda2 /mnt
11. Verify the mounted file systems by running the ├в mount├в command:
sh-2.04# mount
/dev/root on / type unknown (rw,noatime)
none on /proc type proc (rw)
none on /dev/pts type devpts (rw,mode=620)
none on /tmp type ramfs (rw)
/dev/hda2 on /mnt type ext3 (rw)
12. Run the ├в passwddefault├в command as follows:
sh-2.04# /sbin/passwddefault
13. Reboot the switch.
sh-2.04# reboot ├в f
After reboot, login to the switch using username ├в admin├в , password ├в password├в and set the new passwords for root, factory, admin and user accounts.
